Big chickens: According to a poultry industry news website, the weights of broilers (commercially raised chickens) are approximately normally distributed withmean 1417 grams and standard deviation 210 grams. Use the Cumulative Normal Distribution Table to answer the following.(a) What proportion of broilers weigh between 1170 and 1274 grams?(b) What is the probability that a randomly selected broiler weighs more than 1537 grams?(c) Is it unusual for a broiler to weigh more than 1620 grams?Round the answers to at least four decimal places.

μ = population mean = 1417σ = population standard deviation = 210 8)In order to find the proportion…

What is the age distribution of adult shoplifters (21 years of age or older) in supermarkets? The following is based on information taken from the National Retail Federation. A random sample of 895 incidents of shoplifting gave the following age distribution. Estimate the mean age, sample variance, and sample standard deviation for the shoplifters. For the class 41 and over, use 45.5 as the class midpoint. (Round your answers to one decimal place.) Age range (years) 21-30 31-40 41 and over Number of shoplifters 247 344 304 x = s2 = s =

Suppose a subdivision on the southwest side of Denver, Colorado, contains 1,800 houses. The subdivision was built in 1983. A sample of 110 houses is selected randomly and evaluated by an appraiser.

In a recent poll, 45% of survey respondents said that, if they only had one child, they would prefer the child to be a boy. Suppose you conducted a survey of 160 randomly selected students on your campus and find that 79 of them would prefer a boy. Complete parts (a) and (b) below. Click here to view the standard normal distribution table (page 1). LOADING... Click here to view the standard normal distribution table (page 2). LOADING... (a) Use the normal approximation to the binomial to approximate the probability that, in a random sample of 160 students, at least 79 would prefer a boy, assuming the true percentage is 45%. The probability that at least 79 students would prefer a boy is 3636. (Round to four decimal places as needed.)

Newborn Elephant Weights Newborn elephant calves usually weigh between 200 and 250 pounds-until October 2006, that is. An Asian elephant at the Houston (Texas) Zoo gave birth to a male calf weighing in at a whopping 384 pounds! Mack (like the truck) is believed to be the heaviest elephant calf ever born at a facility accredited by the Association of Zoos and Aquariums. If, indeed, the mean weight for newborn elephant calves is 225 pounds with a standard deviation of 45 pounds, what is the probability of a newborn weighing at least 384 pounds? Assume that the weights of newborn el- ephants are normally distributed. Source: www.houstonzoo.org
